Abstract

The ball screw is a main driving component in the CNC machine tools. The ball screw’s structural performances and working conditions will have an important impact on the machining accuracy of CNC machine tools. However, the previous research method can not suffice the precise results’ requirements. So it is very necessary to do an in-depth analysis of the ball screw, which use dynamic research and be combined with the FEA software ANSYS. This article uses the above methods to do the modal analysis, and then gets the intrinsic frequency and the vibration model. It will make an important significance for guiding the practice.
